1. Lay the equatorial mount on its side. Attach the tripod legs one at a time to the mount by sliding the screws installed in the tops of the tr ipod legs into the slots at the base of the mount and tightening the wing nuts finger- tight. Note that the accessor y tra y brack et attachment point on each leg should f ace inward. 2. Tighten the leg lo[...]

Now , release the ten - sioner and tighten the two black nylon screws a couple of turns each to secure the finder scope in place. 13.

6 horizontal position. 5. With one hand on the telescope optical tube, loosen the Dec. lock knob . The telescope should now be able to rotate freely about the Dec. axis. Loosen the tube r ing clamps a f ew tur ns, until y ou can slide the telescope tube f orward and back inside the r ings (this can be aided by using a slight twisting motion on the [...]

Focusing the Finder Scope If , when looking through the finder scope, the images appear somewhat out of focus , you will need to refocus the finder scope f or your ey es. Loosen the lock ring located behind the objective lens cell on the body of the finder scope (see Figure 3a). Back the lock ring off by a fe w tur ns, for now . Ref ocus the finder[...]

8 Use of the R.A. and Dec. Slow-Motion Control Cables The R.A. and Dec. slow-motion control cables allow fine adjustment of the telescope’ s position to center objects within the field of view . Bef ore you can use the cables , you must manually “sle w” the mount to point the telescope in the vicinity of the desired target. Do this by looseni[...]

scale that is on the easter n half of the Dec. setting circle. Retighten the Dec. lock knob . 2. Loosen the R.A. lock knob and rotate the telescope until the R.A. v alue from the star atlas matches the reading on the R.A. setting circle. Retighten the lock knob . Most setting circles are not accurate enough to put an object dead-center in the teles[...]

10 tion of the secondar y mirror (and your ey e) centered in the reflection of the primar y mirror, as in Figure 8a. If anything is off-center , proceed with the follo wing collimating procedure. The Collimation Cap and Mirror Center Mark Y our SpaceProbe 130ST EQ comes with a collimation cap . This is a simple cap that fits on the focuser drawtube[...]

If the entire primar y mirror reflection is not visib le in the sec- ondar y mirror , as in Figure 8c, you will need to adjust the tilt of the secondar y mirror . This is done by alter nately loosening one of the three alignment setscrews while tightening the other two , as depicted in Figure 10. The goal is to center the primar y mirror reflection[...]

ma y be perfectly aligned. It is critical to k eep the star cen - tered, so ov er time y ou will need to make slight corrections to the telescope’ s position in order to account f or the sky’s apparent motion. 7.

Every telescope has a useful limit of magnification of about 2x per millimeter of aper ture. Which comes to about 260x f or the Spac ePro be 130S T . Claim s of high er po wer by som e telescope manuf acturers are a misleading adver tising gimmick and should be dismissed. K eep in mind that at higher powers , an image will always be dimmer and less[...]

D . The Star s Stars will appear like twinkling points of light. Even power - ful telescopes cannot magnify stars to appear as more than a point of light. Y ou can, howe ver , enjoy the different colors of the stars and locate many pretty double and mul - tiple stars. The f amous “Double-Doub le” in the constellation L yra and the gorgeous two-[...]
